Load Modulation for Backscatter Communication: Channel Capacity and Near-Capacity Schemes
Gregor Dumphart, Johannes Sager, Armin Wittneben
In backscatter communication (BC), a passive tag transmits information by just affecting an external electromagnetic field through load modulation. Thereby, the feed current of the…
The Channel Capacity of General Complex-Valued Load Modulation for Backscatter Communication
Gregor Dumphart, Johannes Sager, Armin Wittneben
This paper studies achievable information rates of backscatter communication systems where the tag performs load modulation with a freely adaptable passive termination. We find tha…
The Channel Between Randomly Oriented Dipoles: Statistics and Outage in the Near and Far Field
Gregor Dumphart, Armin Wittneben
We consider the class of wireless links whose propagation characteristics are described by a dipole model. This comprises free-space links between dipole antennas and magneto-induc…
Magneto-inductive Passive Relaying in Arbitrarily Arranged Networks
Gregor Dumphart, Eric Slottke, Armin Wittneben
We consider a wireless sensor network that uses inductive near-field coupling for wireless powering or communication, or for both. The severely limited range of an inductively coup…
Evaluation of Position-related Information in Multipath Components for Indoor Positioning
Erik Leitinger, Paul Meissner, Christoph Rüdisser +2
Location awareness is a key factor for a wealth of wireless indoor applications. Its provision requires the careful fusion of diverse information sources. For agents that use radio…
